Coolant loss with no outside leak, white exhaust smoke or milky oil can mean a head gasket has failed, though other faults share those signs. Find the cause first: with the engine off and cool, look for a milky film on the dipstick or oil cap, and leave compression and combustion-leak tests to a shop. If a failed head gasket is the cause, this set replaces it.
